This is an inexpensive and easy project that you can do. You have to have right supplies, but you don't need the exact supplies we used.
Supplies:
-A box cut in half
-plastic wrap
-wood sticks, skewers or stakes
-tape (clear packing tape works great)
-And the most important thing... plants!
STEPS:
1. Decorate your box if you want to. We learned the hard way it was difficult once the stakes were in place!
2. Carefully tape the stakes in place (see picture)
3. Put plastic wrap on the sides first.
Note: If you have a two-year-old brother, or other little ones, running around messing everything up, please lock them out of the room.
4. Cut a long sheet of plastic wrap.
5. Tape it to the back of the box first; next tape it to the stakes at the top rear, then the top front. The rest should hang down in front.
6. Attach another stake or similar weight to the the end, where the "door" will hang down.
7. Poke some holes for carbon dioxide and oxygen can enter and leave.
And now you have yourself a great greenhouse just ready for plants. Just remember it's pretty small, so don't put big plants in it.
